Question

Quizplus · Accepted Answer

Zanamivir is an antiviral drug that inhibits the activity of neuraminidase, an enzyme on the surface of influenza viruses A and B. This inhibition prevents the virus from cleaving sialic acid on the surface of the host cell, effectively blocking the release of new viral particles and their spread to infect other cells. It is most effective when administered within the first 48 hours of symptom onset.
